Species Overview

European Eel

The European eel undertakes one of nature's most remarkable migrations, traveling 5,000 km from European rivers to the Sargasso Sea to spawn and die. Despite centuries of study, its breeding grounds were only recently confirmed.

Oscar

The oscar is a large, intelligent cichlid native to the Amazon basin. Known for its dog-like personality, it can recognize its owner and may beg for food. Oscars rearrange their tank decor and require spacious aquariums with robust filtration.
